The invention provides a dumper container automatic lifting control system and method. The dumper container automatic lifting control system comprises an oil tank, an oil pump, an electric proportional reversing valve, a lifting oil cylinder, a controller and a control handle. The input end of the oil pump is connected with the oil tank, the output end of the oil pump is connected with the oil inlet end of the electric proportional directional valve, and the oil return end of the electric proportional directional valve is connected with the oil tank. The lifting oil cylinder is connected with the driving end of the electric proportional reversing valve; a lifting control end of the electric proportional reversing valve is connected with the controller; a landing control end of the electric proportional reversing valve is connected with the controller; the controller is connected with the control handle to obtain a lifting or descending control instruction, control the electric proportional reversing valve to operate and execute lifting and descending of the container. Automatic lifting of the container of the dumper is achieved, the system detects whether overload occurs or not through the stress-strain sensor and feeds back the overload in real time, and a lifting hydraulic system and structural parts of the whole dumper are protected.

    本发明提供一种自卸车货箱自动升降控制系统及方法,包括:油箱、油泵、电比例换向阀、举升油缸、控制器以及控制手柄;所述油泵的输入端与油箱连接,油泵的输出端与电比例换向阀进油端连接,电比例换向阀回油端与油箱连接;所述举升油缸与电比例换向阀的驱动端连接;所述电比例换向阀的举升控制端与控制器连接;所述电比例换向阀的降落控制端与控制器连接;所述控制器通过与控制手柄连接,获取举升或降落控制指令,控制电比例换向阀运行,执行货箱的举升和下降。实现了自卸车货箱自动升降,系统利用应力应变传感器检测是否超载并实时反馈,对举升液压系统、整车结构件起到了保护作用。
